Abstract

Flash floods are among the most destructive hydrometeorological hazards in tropical highland regions, yet their spatial risks remain poorly quantified in data-scarce environments. This study assessed flash flood risk in Solok Selatan Regency, West Sumatra (Indonesia), by integrating landform and slope classification with the Topographic Wetness Index (TWI) derived from a 30 m DEM. Historical records of 11 flood events between 2010 and 2020 were used for model validation. The analysis revealed that most of the regency is characterized by moderate flash flood risk, while high-risk zones are concentrated in steep fluvial landscapes. Validation against observed flood locations demonstrated a spatial match of 95.2%, confirming the reliability of the model. In addition, the evaluation of hydrological ecosystem service capacity indicated that over 80% of the landscape has only moderate regulatory function, limiting its ability to buffer runoff. These findings highlight the importance of integrating DEM-based hydrological indices with ecosystem assessments to support more effective disaster risk reduction and spatial planning in tropical highland environments.

Abstract

Indonesia’s disaster mitigation policies have historically relied on technocratic paradigms that often marginalize indigenous knowledge. The research specifically aims to document, analyze, and critically interpret the operationalization of indigenous knowledge across the phases of disaster management: pre-disaster, during-disaster, and post-disaster. Guided by the social-ecological systems theory and cultural resilience framework, a qualitative descriptive approach was employed. Data were collected through field observations, in-depth interviews with community leaders and traditional authorities, and textual analysis of oral and written adat sources. A spatial vulnerability assessment was conducted to contextualize practices within the region’s geomorphological risks. The findings reveal a sophisticated, multi-layered system of risk mitigation embedded in local architecture (e.g., elevated rumah gadang), hydrological infrastructure (tabek, parit nagari), ecological zoning (rimbo larangan), and socio-religious governance (Tigo Tungku Sajarangan). These practices demonstrate high spatial adaptability and cultural coherence but show signs of erosion due to modernization, land-use change, and weakening intergenerational transmission. This study concludes that effective disaster mitigation in high-risk landscapes must transcend engineering-based approaches by integrating indigenous knowledge, normative values, and spatial-cultural contexts into formal disaster risk reduction frameworks. The novelty of this research lies in its holistic documentation of dual-hazard mitigation practices and its proposal of a spatio-cultural corrective to Indonesia’s predominantly technocratic disaster governance.
